When using BBEdit to write a TidBITS article, I actually find another
utility even more useful than Typinator: it’s BBAutoComplete, by Michael
Tsai (whose other invaluable applications include SpamSieve).
BBAutoComplete is a one-trick pony, but that trick is a great one. When
you summon it, usually by pressing some keyboard shortcut, it looks at
the letters preceding the insertion point and then considers all the
other words in your document, seeking one that starts with those same
letters. If it finds one, it completes your letters, turning them into
that word. If that’s the wrong word, press the keyboard shortcut again
to get a different completion. Optionally, BBAutoComplete can look
through other documents open in the same application, and can even
resort to the built-in Mac OS X spell-checker’s word list. However, I
use it only for the frontmost document, and generally only with
peculiar, technical terms (such as “TidBITS,” “SpamSieve,” or
“BBAutoComplete”—yes, I entered all three of those using
BBAutoComplete). BBAutoComplete works in only a few applications,
because serious scriptability is a prerequisite for it to do its magic;
those applications include BBEdit and Microsoft Word. Best of all, it’s
free!
